I have sort of a minor ethical crisis: I'm reviewing the website of a not-to-be-named tile manufacturer who is claiming 40% MRc4 recycled content in their product, due to the reintroduction of scrap and recycled water into their process. I'm real sure that's not a proper claim. Does anyone have experience in "diplomatically" correcting claims like this? Maybe it's none of my business, that it's "buyer beware"? It seems that many manufacturers get defensive about their claims, some to the point of being hostile. Plus, it looks like this company spent a lot of money on their website. Any opinions?
